This is an old thread but mine just started showing the “SD” error. I tried several different SD cards, formatted FAT32 and copied the files over. It will display the first animation then shows the “SD” error. I even tried re-flashing the firmware but that made no difference. This beast has been running for a few years 24/7. I even made spare SD cards with the files in case the current SD card failed but all are showing the error. It also flashes (quickly) the “WIFI” screen right before the “SD” I can even get into the WIFI menu from my browser and force the next animation. If I force the mode to Effects it shows the “WIFI” error every so often (no “SD” error) and the animation does not change.
